I don't know if I have a disadvantage or an advantage when it comes to learning. I can never memorize a mass of stuff. Instead, I have to find a pattern in it and use the pattern to reconstruct it. For example, I could never remember random formulas for e.g. solving the quadratic equation or taking a derivative, but once I figured out how they worked, I could use them right away. This is why I decided to study physics in college: physics has very few pieces of info you have to just memorize.<p>The downside, besides having a horrible time remembering some chemical formula, or the year of the French revolution, is that I also cannot use a formula correctly unless I know how it is derived. I must walk every step of the proof before I can use any part of the formula, otherwise my brain simply refuses to see it correctly.<p>Interestingly enough, I am blessed with very good memory for situations and associations. I can tell you exactly how many olives were in the martini I ordered in July 2008 (3), or quote lines from my favorite shows at every occasion. I just can't remember what my brain seems classify as "generally useless facts".
